Some weeks ago I told you about the sound of EVs and the growing concern regarding quiet cars and pedestrians safety. In 2007, Nissan started real world field research in collaboration with universities and institutions to develop a new type of audio visibility for pedestrians, and particularly for those visually impaired and young children.
